1. An image acquisition method for imaging regions of interest of patients by a radiography system that includes a tube and a detector disposed on opposite positions, said image acquisition method comprising:

  • determining starting and an ending position of a region of interest, and a value of an overlap of the region of interest in two adjacent sub-images;

    calculating a number of sub-images required to be captured, a component of field of view at a direction of tube movement, and positions of the tube and the detector corresponding to each sub-image based on the starting position and the ending position of the region of interest and the value of the overlap;

    moving the tube and the detector to each position and capturing the region of interest to obtain sub-images at the positions; and

    pasting the sub-images together to form an image of the region of interest.
